JOHN B. STANHOPE, OF PHILADELPHIA, PENNSYLVANIA.

BARREL-TRUSSING AND HOOP-DRIVING MACHINE.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed May 7,1904. Serial No. 206,816-

To all whom it may concern:

Be it known that I, JOHN B. STANHOPE, a

citizen of the United States, residing at the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Barrel-Trussing and Hoop-Driving Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of which- Figure 1 is a side elevation partly in section of a barrel trussing machine in which my invention is embodied, the trussing rings hav ing been advanced toward each other a certain distance. Fig. 2 is an enlarged section on line 90-00, Fig. 1. Fig. 3 is a side elevation, enlarged, of a section cut out from the trussing ring. Fig. 4 is a section online yg Fig. 3.

This invention relates to machines for trussing and hoop driving, used in the making of ordinary slack barrels.

The leading feature of the invention comprises the combination with the rings of barrel trussing and hoop-driving machines and means for actuating the same, of a series of independently springcontrolled, radially movable plates mounted on said rings, the inner ends of which plates project normally inwardly beyond the ring, whereby said plates will automatically accommodate themselves to the staves, and will engage and drive on hoo s placed upon the barrel, when the ring is a vanced.

The invention also relates to certain features and details of construction hereinafter described and particularly pointed out.

In the accompanying drawings, I have shown, and shall herein describe my invention as applied to a barrel-trussing machine such as described and shown in United States Letters Patent No. 514,738, granted to me February 13th, 1894. Referring to said drawings, of which Fig. 1, corresponds with Fig. 1 of said patent, and Fig. 2 with Fig. 2 of said patent,-1 denotes each of the two truss-rings, that are respectively connected by rods, 2, to reciprocating heads, 3, and 4, that are adapted to slide upon parallel guidebars, 5, of the frame of the machine. The head, 3, is actuated by a driven shaft, 6, through a crank, 7, thereon, and a connecting rod, 8; and the head, 4, is connected by rods, 9, to a cross-head, 10, that is also slidable upon the guide-bars, 5; which crosshead is actuated by the rotary shaft, 6, through a crank, 11, on the latter, indicated by dotted lines in Fig. 1,and a connecting rod, 12, also indicated by dotted lines. The said cranks are set so that as the shaft rotates, the heads, 3, and 4, will be caused to approach and recede from each other. The heads, 3 and 4, are each provided with contering drums, respectively marked 13 and 14. 14 Fig. 1 is the support for the barrel to be operated upon by the machine.

The foregoing describes, generally, the

The foregoing describes, generally, the con struction of the machine of my said patent.

I now proceed to describe my present im provement, as applied thereto, as follows lWlounted on each of the truss-rings, 1, is a series of similar plates, 15, that are radially movable in suitable guideways of the ring, and are maintained normally projected inwardly beyond the latter, by means of springs 16. In the present construction these plates are L-shaped as seen more clearly in Fig. 4, one limb, 15, thereof passing freely between the ring and an annulus, 17 of less width than the face of the latter, as seen in Fig. 3 and 4, and secured by bolts, 18, Figs. 2 and 3, to said ring. This limb is adapted to slide radially between the ring and annulus, in a groove or guide-way, 19, in the former, the inner face of the limb being substantially flush with the inner face of the ring, as shown. The other limb, 15 of said plate projects over the edge of the ring, as clearly seen in Fig. 4, and, passing freely through a hole in said limb, is a screw-threaded rod, 20, the inner end of which is secured to the ring, 1. Around the part of said rod extending beyond the limb, 15 is a spiral spring, 16, one end of which bears against said limb, and the other end against a nut, 22, or rather, in this instance, against an interposed washer, 23, upon the rod. By adjusting said nut, the tension of the spring may be varied; The tendency of the spring is to maintain the plate inwardly projected beyond the inner edge of the ring. The extent of this projection may, however, be limited by an adjusting nut, 24, Fig. 4, on the rod, between the ring and the under side of limb, 15

Ilaving now described the construction of my invention, I proceed to describe the mode of operation thereof, as follows:premising, however, that the untrussed barrel, 25, to be operated upon, having the end hoops, 26, thereon, is mounted on the support, 14, substantially concentric with the drums, 13; and hoops, 27, to be driven on (which are usually of metal and round in cross-section) have been placed around the barrel, as seen in Figs. 1 and 2; and premising, further, that the heads, 3 and 4 and rings, 1, have been advanced toward each other a certain distance, as shown :At this time the inner ends of the limbs, of the series of plates, 15, are in contact with the barrel-staves, as seen in Fig. 2. These plates, being springcontrolled, and independent of each other, accommodate themselves to any irregularity of the staves, as also seen in said Fig. 2. Now, as the shaft, 6, continues its rotation, the heads, 3 and 4 will continue to approach each other, thus causing the truss-rings, 1, to simultaneously force together the barrel staves in the usual way; the plates, 15, of course, partaking of the inward movement of the rings. hen the faces of the limbs, 15 meet the hoops, 27, they will carry forward the latter and. finally drive said hoops tightly on the barrel. However loose these hoops be on the barrel or staves at first, or whether they be canted thereon in either direction, is immaterial, as the plates, 15, will, as they advance, bring said hoops in required position, or plane, that is, at right angles to the major axis of the barrel. The barrel having been trussed and hooped, the heads 3 and 4, and their adjuncts, will, as the shaft, 6, continues to rotate, recede from each other, whereupon when the retraction has been completed, the barrel may be removed from the machine. I usually make on the forward side of the limb, 15 of each of the plates, 15, adjacent to the inner end thereof a groove, 28, and on the like side of the ring, 1, between limbs,

15 a groove, 28*; sothat when the plates, 15, are pressed outwardly to the full extent or thereabout, the grooves, 28, 28", will form a continuous circular groove, to receive the hoop, 27, in the driving operation, the said groove being of less depth than the diameter of the hoop, as seen in Fig. 4. Thus the hoop will be firmly held and prevented from expanding at any particular point or points.

Having described my invention, I claim as new and desire to secure by Letters Patentz- Means for driving hoops on barrels, consisting of the combination of the rings, means for reciprocating the same toward and from each other,the series of independent L-shaped radially movable plates mounted on said rings respectively, one of the limbs of said plates being adapted to slide radially in suitable guide-ways of .a ring, and the other limb thereof extending over said ring, the rod secured to the latter and passing through the last-mentioned limb, a stop for limiting the inward movement of the plate, and the spring bearing against said lastmentioned limb and tending to maintain the plate projected inwardly, substantially as and for the purpose set forth.

In testimony whereof, I have hereunto affixed my signature this sixth day of April, A. D. 1904.

JOHN B. STANHOPE.
